LineNearestPoint()

template<class TPointType , class TGeometryType >

static Point Kratos::NearestPointUtilities::LineNearestPoint ( const TPointType &  rPoint, const TGeometryType &  rLine  )

inlinestatic

Finds the nearest point to the given point on a line segment.

It first projects the point into the line. If the porjceted point is inside the segment boundary it returns the projected point. If not it returns the nearest end point of the line.

Template Parameters

Type	of the Point
TGeometryType	The type of the line. Assumes to have [] access and IsInside method

Parameters

rPoint	The query point which we want to get nearest point to it on the line
rLine	The line in which we want to find the nearest point to rPoint

Returns

The nearest point to rPoint

operator=()

NearestPointUtilities& Kratos::NearestPointUtilities::operator= ( NearestPointUtilities const &  rOther )

delete

Assignment operator.

TriangleNearestPoint()

template<class TPointType , class TGeometryType >

static Point Kratos::NearestPointUtilities::TriangleNearestPoint ( const TPointType &  rPoint, const TGeometryType &  rTriangle  )

inlinestatic

Finds the nearest point to the given point on a trianlge.

It first projects the point into the triangle surface. If the porjceted point is inside the triangle it returns the projected point. If not it returns the nearest point on the edges of the triangle. Dividing the plane of the triangle in 7 zones and find the nearest reflecting those zones
